The Armourcoat Acoustic® Plaster System is designed to optimise the acoustics of interior spaces.
From restaurants, theaters, offices, classrooms, hotel receptions and private residences, the use of hard sound reflective surfaces such as glass, wood and stone can cause excessive sound reverberation which leads to unpleasant noise levels. The correct control of sound will create a calmer and more pleasant environment.
The Armourcoat Acoustic® Plaster System offers a clean flat and smooth mineral surface that can be applied seamlessly over large expanses to both flat and curved surfaces. It offers excellent sound absorption - to class 'A' Noise Reduction Coefficient.
The Armourcoat Acoustic® Plaster System is suitable for use in both commercial and residential interior projects including major transport hubs, restaurants, bars and nightclubs, cinemas and theaters, shopping centers and retail units, leisure facilities such as swimming pools and gymnasiums, open plan office environments, corridors and walkways, toilet and washroom lobbies, music rooms, open plan entrance halls and living spaces.
The Armourcoat Acoustic® Plaster System was the first acoustic plaster system to be granted the Quiet Mark Award in 2019 - the international mark of approval from the Noise Abatement Society Charitable Foundation. Quiet Mark is the international award programme and system of support for brands and consumers. Through its pioneering acoustic tests, the organisation awards its distinctive Purple Q Mark to products and services that show excellence in low-noise and high-performance.
Armourcoat are delighted to support Quiet Mark's 'Acoustics Academy' as launch partner and their highly regarded podcast series.

The Armourcoat Acoustic® Plaster System comprises of a special mineral wool composite panel that is bonded onto the substrate and finished with a seamless layer of the Armourcoat Acoustic plaster. Armourcoat’s considerable expertise in the formulation of marble based plaster finishes have created an elegant finish that appears smooth and even but still allows sound energy to pass through the surface. This enables sound to be absorbed and attenuated in the layer of mineral wool beneath. The Armourcoat Acoustic® Plaster System can be pigmented to a range of standard or custom colors. Firmly established as a recognised and approved acoustic system in the UK, worldwide availability is currently being implemented.
Excellent acoustic performance
Independent tests were carried out in the UK on the Armourcoat Acoustic® Plaster System to determine the Sound Absorption Coefficient (αs), conducted in accordance with European Standard EN ISO 354. Single figure ratings of sound absorption performance, known as the Weighted Sound Absorption Coefficient (αw), Sound Absorption Class, Sound Absorption Average (SAA) and Noise Reduction Coefficient (NRC) are derived from these measurements in accordance with European Standard EN ISO 11654 and American Standard ASTM C423-17. Tests were carried out by the AIRO Acoustics Laboratory, a UKAS accredited testing laboratory No. 0483, on 18th December 2019 and 22nd April 2020. The Armourcoat Acoustic® Plaster System achieved BS EN ISO 354:2003 Weighted Sound Absorption Coefficient (αw) of 0.85, class B (28mm system) to 0.95, class A (48mm system).

Excellent environmental performance
Armourcoat Acoustic® panels are made in the UK to exacting quality standards - and are ready for immediate installation. The mineral wool panels incorporate 70% recycled content, with the basecoat made from expanded glass with 85% recycled content, and the topcoat plaster made from 80% recycled marble. The system contains no VOCs and is resistant to bacteria, mold and mildew.
Excellent thermal performance
Armourcoat Acoustic® mineral wool panels have a lambda value of 0.032 W/mK, to provide excellent thermal performance and reduce heat loss through the building envelope.
